BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent No. 644,147, dated February27, 1900.

Application filed December 11, 1899. Serial No. 739,865. (No model.)

To aZZ whom, it 777/6111] concern.-

Beit known that I, EDWARD D. RooKwELL, a citizen of the United States,residing at Bristol, in the county of Hartford and State of Connecticut,have invented a new and useful Bicycle-Bell, of which the following is aspecification.

My invention relates to improvements in bicycle-bells in which theoperating mechanism is actuated by means of power stored within thebell, suitable devices being employed to allow the mechanism to act atthe will of the operator; and the objects of my improvement are toprovide a bell having the operating mechanism compactly arranged in amanner to provide extreme strength and durability and to insure theoperation of the parts at all times. I attain these objects by themechanism illustrated in the accompanying drawings, in which Figure 1 isa View in side elevation of a bicycle-bell embodying my invention. Fig.2 is a top or plan view with the gong removed and the upper plate brokenaway to show construction. Fig. 3 is'a view in longitudinal sectionthrough the device with the gong and a portion of the works removed.Fig. 4 is a detail bottom view of the bottom plate, showing thespring-case, the spring removed.

In the accompanying drawings the numeral 1 denotes the base, 2 the gong,3 the clamp, and 4 the handle-bar,'of a bicycle to which the bell may besecured, all these parts being of any usual and well-known construction.

A stud 5, secured in an opening in the base, provides means forattachment of the clamp 3 and also serves as a step-bearing for agongpost 6, that is rotatably mounted in the structure. A bottom plate 7is secured to the base, and a top plate 8 is supported on posts securedto the bottom plate, these two plates and the step-bearin g affording afirm support for the gong-post 6. The gong 2 is secured to the post inany preferred manner, interengaging screw-threads providing a convenientmeans of attachment.

A spring-case 9, preferably formed in the shape of a spider, as shown inFigs. 3 and 4 of the drawings, is mounted on the gong-post 6, and amainspring 10 is located in the springcase, with its inner end securedto the gongpost and its outer end secured to the springcase. A gear-wheel 11 is secured to the spring-case and is in mesh with a pinion 12,secured to the lower end of the arbor 13 and underneath the bottom plate7. This arbor has a bearing at each end in the top and bottom plates 7and 8 and bears a gear-wheel 14, in mesh with another member of anoperating-train, that includes an escapement consisting of a scape-Wheel15, in engagement with the teeth of a verge 16, to which is secured ahammer-lever 17, bearing on its end a hammer adapted in the vibratingmovement of the verge to sound the gong.

A spring 18 is secured to the upper plate and projects in position tohold the hammerlever from vibrating movement. The end of the spring liesin the path of movement of a push-button 19, that in its inward movementreleases the spring from engagement with the hammer-lever and allows themechanism to act under the force of the mainspring 10.

A ratchet 20 is secured to the gong-post 6, and a spring-actuated pawl21 is secured to the upper plate 8 and is in engagement with the teethof the ratchet-wheel to hold it againstbackward movement under the forceof the mainspring 10.

As a result of the improvement it will be seen that an extremely-strong,cheap, and ef= fective device is obtained, the gong remaining stationaryduring the ringing of the bell and rotating only during the winding0pera= tion.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In combination in a bicycle-bell, a cup shaped base, a bottom plate,forming a cover for the base, a gong-post extending through the bottomplate, a spring-case mounted on the post, a mainspring with one endsecured to the post and the other end secured to the spring-case,agear-wheelsecured to the spring case, a top plate, an arbor mounted insaid plates and projecting through the bottom plate, a pinion secured tothe arbor under the bottom plate, a gear-wheel secured to said arborbetween the plates, a vibrating hammerlever operatively connected withsaid lastmentioned gear-wheel and bearing a hammer, a spring restingagainst the hammer-lever, a

push-button adapted to engage the spring, means for holding thegong-post against backward movement, and a gong secured to the upper endof the post.

2. In a bicyc1e-bell,in combination, a cupshaped base, a bottom plateforming a cover for the base, a gong-post extending through the bottomplate, a spring-case rotatably mounted on the post, a mainspring withits inner end secured to the post and its other end secured to thespring-case, a gear-Wheel secured to the spring-case and engaging apinion on an arbor extending through the bottom plate, the arbor bearinga gear-wheel located above the bottom plate, a vibrating hammer-leveroperatively connected with said pinion and bearing a hammer, a springnormally holding the hammer-lever against movement, a push-buttonadapted to disengage the spring, whereby the hammerdever is released,means for holding the gong-post against backward movement, and a gongsecured to the upper end of the post.

3. In a bicycle-bell, in combination, a cupshaped base, a bottom plateforming a cover for the base, a gong-post extending through the bottomplate, aspring-ease located in the chamber under the bottom plate androtatably mounted on the gong-post, a mainspring with its inner endsecured to the post and its other end secured to the spring-case, agearwheel secured to the springcase and engaging a pinion on an arborextending through the bottom plate, the arbor bearing a gearwheellocated above the bottom plate, a vibrating hammer-lever operativelyconnected with said pinion, a pawl on the top plate with its free endengaging the teeth of said ratchet and bearing a hammer, a springresting against the hammer-lever, means for releasing the spring fromengagement with the hammer-lever, a ratchet secured to the gongpostunderneath the top plate, and a gougsocared to the upper end of thegong-post.
